Title: Semiconductor substrate and its manufacture
Inventor: KIKUCHI HIROMASA
IPC: H01L27/12
Filed: 1995-12-28
Abstract: PURPOSE: To obtain an optimum semiconductor substrate as a substrate for monolithically integrating a vertical power element and a control circuit element. CONSTITUTION: A cavity 3 is formed between an insulating layer 2 in a region 8 for forming a control circuit element and a single crystal silicon substrate 4, and bonding surfaces 1a, 4a of the single crystal silicon substrates 1, 4 are bonded to each other. Since the sticking of a region in which a vertical power element is formed is performed by mutually sticking flat single crystal silicon surfaces, voids (unbonding parts) are not generated in a bonding surface of the region in which the vertical power element is formed. Thereby, a semiconductor device having a perfect junction wherein electric conduction in the direction perpendicular to the bonding interface is present can be realized.
